The circulating current is one prominent example of these challenges that may cause serious damage to equipment. Hence, control algorithms must ensure that the current is shared equally or in proportion to the power ratings of the parallel inverters, while mitigating the circulating current. Another challenge is that all parallel inverters should have equal output voltage, phase, and frequency. This paper proposes a new method to control parallel UPS modules. The method is based on regulating the capacitor voltage of the LCL output filter of each inverter to indirectly control its output current. The method can achieve high accuracy in terms of equal current distribution between the power sources. Simulation and experimental results are presented to verify the theoretical analysis.本誌: IEEJ Journal of Industry Applications Vol.6 No.4 （2017）本誌掲載ページ: 258-267 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/6/4/6_258/_article/-char/ja/
